msi or gigabyte are the best brand for gpu, giga is known to be the best overall for dissipation, and msi is slightly more silent, your choice

I thought Sapphire is the best card for mining. But everybody has different opinions. I use Sapphire mainly.

And I'm not sure if the PSU power is enough.

One question about Watt per card an MHs

If I use the 380 or 390
I know there are 10mh between them. What are the power consumption?
380 get 20mhs
And 390 30mhs as I know...

the consuption is probably 50% more

Not quite. My 390 is using ~283, while my friends 380 is using ~240 (calculated by using a power meter while it was running on intergrated gpu and with the 390/380 100% usage). Thats not too much of a difference, for the hashrate bonus. Also I've noticed with some 380's its hard to get them to 20, 18-18.5 had no issues.

it's better to use 280x, which is 25 per 240, 380 is bad even a 970 is better

you don't need two 1200 wat, that is overkill lol

1 1500 or 1600 is enough, 6 gpu are 1200 watt, you can just limit the tdp and save money on the psu, which is expensive

Thanks Guys.

So Sapphire would also be my choice. R9 390.

Which Voltage and Clock I have to use to get about 30 MH?
I'm planning to put 2 x 1000W PSU... I'm trying to get the W per Card to 200W. Not sure if it's possible with a R9 390.

Saw in a topic someone got 35-40MHS with a 390 but he used this:

Turned Constant Voltage off ( was causing instability when taking memory clock over 1640) Core Voltage +100 Power Limit +50 Core Clock 1200 Mem Clock 1650 Fan Speed 100

Thing is humming along between 34-36MH/s stable and hasnt crashed at these settings yet, running over 12Hours.

I have 6 x MSI R9 390 with PRO BTC H81 and Powered ribbon risers (unpowered)

from what i know you need 2 x1200w PSU and something like 600w PSU for the Mobo!

I wish you all the best with your set up and driver install etc.. its gonna be a nightmare.. take it from me

I have a total of 30 x MSI R9 390 cards and 5 PRO BTC H81 Mobos. i only managed to get one of the rigs running as it should.. and that is without any OC.. because afterburner is not allowing asrock motherboard or Intel shipset...I guess they prefer us to buy MSI Mobos... so its all crap :-/

Let me now if you have you managed to configure your set up.. looking forward to that :-)

Both my rigs are running AsRock mobos (however Z97 Extreme6 and Z77 Extreme4) and I OC'd fine. The MSI 390 were a bad choice though as their cooling is not as effective as say Sapphire's is. I mean they're not totally bad, its just I had a better experience with Sapphire.

Okay thanks. And what about the GPU.

Should I use 390 or the 390x? Msi or Sapphire? Or any other brand?
Are two 1000w PSU enough or one 1600W LEAP?

390 is better for Ethereum miniing than 390X. If you use 6 R9 390, you need at least 1500W PSU. It is cheaper to have two 1000W.

390 Sapphire. I use that (Nitro backplate version) and do 31MH/s at 70c 70% fan (almost no noise). Very good fans/cooling. I'd take 2 1kw's

1600w, 1k is not enough for 6 gpu, you don't want to stress your psu and use usb riser

For most mining, 4GB is enough. Powered riser is very good for most mining rigs. 32 GB is enough, but for ether mining, you have to remove the DAG every few weeks to keep the disk usage low.
